Description
CoreWeave is The Essential Cloud for AI. As a Senior Systems Engineer on the Systems Engineering team, you will own and evolve our test framework, a Kubernetes-native system that qualifies host images and infrastructure on real hardware.
Responsibilities:
- Own and extend the test framework that qualifies host images and infrastructure on real hardware
- Broaden what the framework qualifies, including HPC and fabric verification, Slurm-on-Kubernetes, and further down the stack into firmware and hardware
- Keep the pipeline fast, hermetic, and trustworthy, ensuring engineers trust the signal
- Own the results and reporting path end to end, including structured test results, storage, dashboards, and triage surfaces
- Explore AI-native testing, including LLM-driven log triage, failure classification, and regression detection
- Collaborate with firmware, kernel, imaging, and HPC teams to embed testing into their release process
Requirements:
- 3+ years of experience building test infrastructure, systems software, or platform tooling at scale
- Fluent in Python, with either proven Rust experience or a strong systems background
- Comfortable operating in a Kubernetes environment and reasoning about software deployment and testing
- Solid Linux systems background, including boot chain, kernel and drivers, and low-level debugging
- Real testing discipline, with strong opinions about flakiness, hermeticity, and signal
- Clear communicator who treats the test framework as a product other engineers want to use
Preferred:
- Rust and Kubernetes-native workflow orchestration experience
- HPC or large-cluster experience, including InfiniBand/RoCE, GPU/accelerator validation, or performance-regression frameworks
- Slurm or Slurm-on-Kubernetes experience
- Firmware or lower-level hardware validation experience
- Applying LLMs to test workflows, including triage, failure classification, and flaky-test detection
